  • Introduction to Iron ore Pellets and Pelletizing processes

    Raw material preparation – During the process for pelletization iron ore concentrate from iron ore beneficiation plant is dried and heated to around 120 deg C. The dried material is fed to the ball mill for grinding. Concentrate/ground iron ore of typical size 80 % less than 45 microns (0.045 mm) with a moisture content of around 9 % is

  • Introduction to Iron ore Pellets and Pelletizing processes

    Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

  • Steel Manufacturing Process

    The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel scrap.

  • Cost Effectiveness Analysis of HYL and Midrex DRI

    Apr 27, 2016· Steel Making Process and CO 2222 EmissionsEmissionsEmissions Steel is primarily made by one of two processes: the blast - basic oxygen furnace (BF-BOF), and the electric arc furnace (EAF). The BF-BOF is a two-step process. First, in the blast furnace, mined iron ore is combined with limestone and coke to form molten iron.

  • Direct reduced iron - Wikipedia

    Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

  • Manufacturing Process of Cast Iron Castings

    Used by itself, pig iron has few uses due to its brittle nature. Alloyed with other metals, pig iron takes on new uses. Making Cast Iron The term cast iron is generally used to describe grey cast iron, but it can also describe a whole group of alloys too. The surface color of the cast iron is often used to identify it.
